[PATCH 0/4] Miscellaneous changes to aid in troubleshooting

[Glenn Washburn]

These are pretty self-explanatory. They've been useful in debugging grub
issues. Note that patch #2 and #3 are particularly synergistic.

Also a note about patch #4. It was used in a version of patch #3, though not
any more. I decided to leave it in this patch series because it enhances
grub_strword without any downsides (that I'm aware of).

  error: Add grub_errno to printed error message
  misc: Add debug log condition to log output
  misc: Allow selective disabling of debug conditionals
  misc: Change grub_strword to return a string like grub_strstr
